Updated interagency sea level rise scenarios

Scenarios, Coasts

Throughout 2021, the interagency Sea Level Rise Task Force, under the auspices of USGCRP’s CoastsIG and the Subcommittee on Ocean Science and Technology, engaged in extensive collaboration to produce the 2022 Sea Level Rise Technical Report, which provides the most up-to-date sea level rise projections for all U.S. states and territories by decade for the next 100 years and beyond (Sweet et al., 2022). The report projects that sea levels along the U.S. coastline will rise an additional 10–12 inches by 2050, with regional variation. Agencies at the federal, state, and local levels use these projections in planning to manage risks related to sea level rise. A suite of federal tools, including NASA’s Interagency Sea Level Rise Scenario Tool and NOAA’s Sea Level Rise Viewer, is making these data accessible and customizable. The results will also underpin discussions of coastal impacts in NCA5. The Sea Level Rise Task Force includes members from NOAA, NASA, EPA, DoD, FEMA, USGS, and USACE, as well as several academic institutions.
